While we will still build for 18.04, we will now stop testing against it. Instead, we will test against 20.04, the next EOL release after 18.04. Once Ubuntu 18.04 is EOL, any references to it will also be removed. Note that 18.04 support was already deprecated in Dokku 0.28.0, so this change is just acknowledging that deprecation.

# DreamHost Cloud Server Installation Notes
|
|
|
|
Cloud-init script can be used to automate installation of Dokku on
|
|
Dreamhost (or any other OpenStack-compatible cloud with minimal
|
|
changes).
|
|
|
|
A new server instance can be created on DreamHost Cloud from the command line
|
|
using OpenStack client or from the web UI and with the same command
|
|
use a cloud-init script to install Dokku. Install the [OpenStack
|
|
CLI](https://help.dreamhost.com/hc/en-us/articles/216185658-How-to-Install-the-OpenStack-command-line-clients),
|
|
download the [DreamHost Cloud credentials
|
|
file](https://iad2.dreamcompute.com/project/access_and_security/api_access/openrc/)
|
|
before proceeding and make sure your public SSH key is added to the
|
|
cloud.
|
|
|
|
```sh
|
|
source openrc.sh # Set the environment variables for DreamHost Cloud
|
|
```
|
|
|
|
This allows OpenStack client to connect to DreamHost API endpoints.
|
|
The command below creates a new server instance named `my-dokku-instance`
|
|
based on Ubuntu 20.04, with 2 GB RAM and 1 CPU (the flavor called
|
|
`supersonic`), opening network port access to HTTP and SSH (the
|
|
`default` security group), and the name of the chosen SSH key. This
|
|
key will be automatically added to the new server in the
|
|
`authorized_keys` for the default SSH user (`ubuntu`), and it will
|
|
be reused by Dokku.
|
|
|
|
```sh
|
|
openstack server create \
|
|
--image Ubuntu-20.04 \
|
|
--flavor gp1.supersonic \
|
|
--security-group default \
|
|
--key-name $YOUR_SSH_KEYNAME \
|
|
--user-data dokku-cloudinit.sh \
|
|
my-dokku-instance
|
|
```
|
|
|
|
The content of dokku-cloudinit.sh script contains instructions to add
|
|
Docker and Dokku's apt repositories and install Dokku with the proper
|
|
debconf options set. Don't forget to add the FQDN for your application
|
|
server:
|
|
|
|
```yaml
|
|
#cloud-config
|
|
|
|
apt:
|
|
sources:
|
|
source_dokku:
|
|
source: 'deb https://packagecloud.io/dokku/dokku/ubuntu/ $RELEASE main'

Shortly after running the create command you will get a confirmation that the
|
|
instance has been created, and after about a minute it should be ready to login. Check the IP of the instance through the web UI or by running:
|
|
|
|
```sh
|
|
nova list
|
|
```
|
|
|
|
SSH with the `ubuntu` username and the public key previously added.
|
|
Keep in mind that if you logged in quick enough Dokku might still be installing in the background, and not be ready. The installation takes a few minutes.
